Description
BACKGROUND OF THE INVENTION
1. Technical Field
[0001] The present invention relates to the field of
two-dimensional code testing, in particular to a two-dimensional
code card grabbing and storage device and method.
2. Description of Related Art
[0002] At present, electronic payment based on two-dimensional
codes is becoming more and more popular. The key of successful
payment lies in the recognition rate of cameras, and thus the
capacity to recognize two-dimensional codes with a large quantity
of different information, gray scales and completeness levels of
cameras needs to be tested. In order to achieve automatic testing,
a device must be designed for storing, grabbing, discharging and
automatically testing two-dimensional code cards (the
two-dimensional code cards refer to IC cards printed with
two-dimensional codes). In the prior art, vacuum chucks or
mechanical clamping devices were mainly used for grabbing
two-dimensional code cards, but certain power resources are needed,
increasing equipment costs and reducing the moving flexibility of
the device.
[0003] Nano micro-suction materials are a new generation of glue
materials recently developed based on the following principle. The
reason why geckoes can resist earth's gravity and cling to the
surfaces of objects is that tiny villi, called bristles, are
densely grown on the feet of the geckoes and hundreds or thousands
of protrusions with diameter of 0.25 microns exist at the tail end
of each bristle. This fine structure makes the bristles extremely
close to surface molecules of objects on which the geckoes climb,
and thus molecular attraction is generated. Based on this
principle, the nano micro suction materials can firmly create
suction on flat and smooth rigid objects when touching the flat and
smooth rigid objects.
BRIEF SUMMARY OF THE INVENTION

invention provides a two-dimensional code card grabbing and storage
device and method, which can sequentially grab, discharge, sort and

connected with a mechanical claw controlled by a mechanical claw
driving mechanism. The mechanical claw is disposed beside the
second side plates. The distance between the two first baffles and
the distance between the two second baffles are greater than the

plates are fixed to the horizontal base plate through bolts, the
two first baffles are perpendicularly fixed to the two first side
plates through bolts, and the two second baffles are
perpendicularly fixed to the two second side plates through
bolts.
[0010] The present invention further provides a grabbing and
storage method of the two-dimensional code card grabbing and
storage device. The grabbing and storage method comprises the
following steps:
[0011] Step S1, the grabbing plate is fixed to the mechanical claw,
and the mechanical claw is driven by the mechanical claw driving
mechanism to drive the grabbing plate to move to a position beside
the second side plates;
[0012] Step S2, the grabbing plate is moved by the mechanical claw
driving mechanism to a position above the second guide plate where
the two-dimensional code cards are stacked so as to grab the
two-dimensional code cards;
[0013] Step S3, the grabbing plate grabs the uppermost
two-dimensional code card on the second guide plate through the
nano microsuction material;
[0014] Step S4, the grabbing plate is moved by the mechanical claw
driving mechanism to a position in front of a test device after
grabbing the uppermost two-dimensional code card, and then the

is used for storing tested two-dimensional code cards, a second
guide plate is used for storing to-be-tested two-dimensional code
cards, and the first guide plate and the second guide plates are
disposed obliquely, so that the two-dimensional code cards are
sorted automatically under the effect of gravity. In addition, the
distance between the two first baffles and the distance between the
two second baffles are greater than the width of a grabbing plate
and smaller than the width of the two-dimensional code cards, so
that the tested two dimensional code cards are separated from the
grabbing plate under the effect of the first baffles and a
mechanical claw driving mechanism. When close to the
two-dimensional code cards, the grabbing plate can automatically
grab the two-dimensional code cards through a nano micro suction
material on the grabbing plate.

DETAILED DESCRIPTION OF THE INVENTION
[0025] A further description of the present invention is given as
follows with the drawings and specific embodiment.
[0026] As is shown in FIG. 1 and FIG. 2, a two-dimensional code
card 10 grabbing and storage device comprises a horizontal base
plate 1. First side plates 2 and second side plates 3 are
sequentially disposed on the front side and the rear side of the
horizontal base plate 1 separately in the horizontal direction and
perpendicularly fixed to the upper surface of the horizontal base
plate 1. The first side plates 2 are lower than the second side
plates 3. First baffles 4 extending inwards are oppositely and
perpendicularly disposed on the outer sides of the two first side
plates 2, and second baffles 5 extending inwards are oppositely and
perpendicularly disposed on the inner sides of the two second side
plates 3. A first guide plate 6 used for storing tested
two-dimensional code cards 10 is upward obliquely disposed between
the two first side plates 2, and a second guide plate 7 used for
storing to-be-tested two-dimensional code cards 10 is obliquely
disposed upward between the two second side plates 3. The
two-dimensional code card grabbing and storage device further
comprises a grabbing plate 8 used for grabbing the to-be-tested
two-dimensional code cards 10. A nano microsuction material 9
adheres to one side of the grabbing plate 8, and the other side of
the grabbing plate 8 is fixedly connected with a mechanical claw
controlled by a mechanical claw driving mechanism. The mechanical
claw is disposed beside the second side plates 3. The distance
between the two first baffles 4 and the distance between the two
second baffles 5 are greater than the width of the grabbing plate 8
and smaller than the width of the two-dimensional code cards
10.
[0027] From the above description, the present invention has the
following beneficial effects: The first guide plate is used for
storing the tested two-dimensional code cards 10, the second guide
plate is used for storing the to-be-tested two-dimensional code
cards 10, and the first guide plate and the second guide plate are
disposed obliquely, so that the two-dimensional code cards 10 are
sorted automatically under the effect of gravity. Furthermore, the
distance between the two first baffles 4 and the distance between
the two second baffles 5 are greater than the width of the grabbing
plate 8 and smaller than the width of the two-dimensional code
cards 10, so that the tested two-dimensional code cards are
separated from the grabbing plate 8 under the effect of the first
baffles 4 and the mechanical claw driving mechanism. The grabbing
plate 8 can automatically grab the two-dimensional code cards 10
through the nano micro suction material 9 on the grabbing plate 8
when close to the two-dimensional code cards 10. The grabbing plate
8 is controlled by a small existing universal three-coordinate
robot comprising a mechanical claw capable of moving in the X-axis
direction, Y-axis direction and Z-axis direction and a mechanical
claw driving mechanism used for driving the mechanical claw.
[0028] The nano microsuction material 9 adheres to one side of the
grabbing plate 8 through fixing glue and is a nano micro-suction
tape.
[0029] Furthermore, in this embodiment, one end of the first guide
plate 6 is obliquely fixed upward to the two first baffles 4, and
one end of the second guide plate 7 is obliquely fixed upward to
the two second baffle 5. The two sides of the first guide plate 6
are fixedly connected with the inner side faces of the two first
side plates 2, and the two sides of the second guide plate 7 are
fixedly connected with the inner side faces of the two second side
plates 3.
[0030] In this embodiment, the first guide plate 6 is fixed between
the bottoms of the two first side plates 2, and the second guide
plate 7 is fixed between the middle portions of two second side
plates 3.
[0031] In this embodiment, the first side plates 2 located on the
front side of the horizontal base plate 1 are disposed adjacently,
the second side plates 3 located on the rear side of the horizontal
base plate 1 are disposed adjacently, and the inner sides of the
two first side plates 2 are connected with the outer sides of the
two second baffles 5.
[0032] In this embodiment, the first side plates 2 and the second
side plates 3 are fixed to the horizontal base plate 1 through
bolts, the two first baffles 4 are perpendicularly fixed to the two
first side plates 2 through bolts, and the two second baffles 5 are
perpendicularly fixed to the two second side plates 3 through
bolts.
[0033] The present invention further provides a grabbing and
storage method of the two-dimensional code card 10 grabbing and
storage device. The grabbing and storage method comprises the
following steps:
[0034] Step S1, the grabbing plate 8 is fixed to the mechanical
claw, and the mechanical claw is driven by the mechanical claw
driving mechanism to drive the grabbing plate 8 to move to a
position beside the second side plates 3;
[0035] Step S2, the grabbing plate 8 is moved by the mechanical
claw driving mechanism to a position above the second guide plate 7
where the two-dimensional code cards 10 are stacked 10 so as to
grab the two-dimensional code cards 10;
[0036] Step S3, the grabbing plate 8 grabs the uppermost
two-dimensional code card 10 on the second guide plate 7 through
the nano microsuction material 9;
[0037] Step S4, the grabbing plate 8 is moved by the mechanical
claw driving mechanism to a position in front of a test device
after grabbing the uppermost two-dimensional code card 10, and then
the two-dimensional code is tested;
[0038] Step S5, after the two-dimensional code is tested, the
grabbing plate 8 is moved by the mechanical claw driving mechanism
to a position above the two first side plates 2 to be matched with
the first baffles 4, the two-dimensional code card 10 is clamped
between the two first baffles 4, and the grabbing plate 8 is driven
by the mechanical claw driving mechanism to make the
two-dimensional code card 10 fall onto the first guide plate 6 from
the grabbing plate 8; and
[0039] Step S6, whether all the two-dimensional code cards 10 are
grabbed or not is observed; if yes, the test is ended; or if not,
Step S2 is performed.
[0040] The specific implementation process of the present invention
is as follows. As is shown in FIG. 3, the two-dimensional code card
10 is grabbed, specifically, a two-dimensional code card 10 storage
bin is defined by the two first side plates 2 and the two first
baffles 4, and a two-dimensional code card 10 discharge bin is
defined by the two second side plates 3 and the two second baffles
5; the grabbing plate 8 is moved by the mechanical claw to a
position a (namely the position between the two second side plates
3) of the two-dimensional code card 10 discharge bin, the nano
microsuction material 9 on the grabbing plate 8 is stuck to the
two-dimensional code card 10 located on the second guide plate 7,
the grabbing plate 8 is then moved by the mechanical claw to a
position b above the second side plates 3, and thus the
to-be-tested two-dimensional code card 10 is grabbed without a
grabbing power source. Afterwards, the two-dimensional code card 10
is moved to a position in front of the test device, and then the
two-dimensional code is tested. After the two-dimensional code is
tested, the tested two-dimensional code card 10 is moved by the
mechanical claw to a position c beside the first side plates 2.
[0041] As is shown in FIG. 4, the two-dimensional code card 10 is
stored, specifically, the tested two-dimensional code card 10 is
stored by moving the grabbing plate 8 from a position A, to a
position B and finally to a position C by the mechanical claw; at
the position B, the width of the two-dimensional code card 10 is
greater than the distance between the two first baffles 4 while the
width of the grabbing plate 8 is smaller than the distance between
the two first baffles 4, so that when the grabbing plate 8 passes
between the two first baffles 4, the two-dimensional code card 10
will be blocked in the two-dimensional code card 10 storage bin by
the first baffles 4, and thus the tested two-dimensional code card
10 is discharged; and the two-dimensional code card 10 passes
through the first guide plate 6 when falling down and then can be
placed in the two-dimensional code card 10 storage bin in order
under the effect of the upward inclined first guide plate 6, and
thus the tested two-dimensional code cards 10 are automatically
sorted.
[0042] In conclusion, the two-dimensional grabbing and storage
device and method of the present invention can grab two-dimensional
code cards without grabbing power and can also discharge and
automatically sort tested two-dimensional code cards.
[0043] The purposes, technical scheme and advantages of the present
invention are further described in detail with the preferred
embodiment mentioned above. It would appreciate that the embodiment
mentioned above is only one preferred embodiment of the present
invention and is not used for limiting the present invention, and
any modification, equivalent substitute and improvement made based
on the spirit and principle of the present invention should fall
within the protection scope of the present invention.
